MoonPay’s Open Wallet Standard unifies AI agent wallets across chains

MoonPay has launched the Open Wallet Standard (OWS), an open-source wallet system aimed at AI agents. The Open Wallet Standard is designed to unify fragmented agent wallets so agents can hold value, sign transactions, and pay for services across multiple blockchains without exposing private keys. MoonPay previously built “MoonPay Agents,” a non-custodial wallet, but the lack of a universal standard limited interoperability. OWS introduces a single encrypted vault per user. Keys are kept encrypted at rest, decrypted only in memory for signing, and wiped immediately after. It also uses policy-gated signing, enabling spending limits, contract allowlists, and chain-specific restrictions for operators. OWS supports EVM chains plus Solana, Bitcoin, Cosmos, Tron, TON, Filecoin, and the XRP Ledger. A single seed phrase can generate accounts across chains, while integrations include agent frameworks such as Claude, ChatGPT, and LangChain, with SDKs for Node.js/Python and command-line interfaces. In market context, Solana (SOL) is trading near a key technical zone: it held above $88.57 support after rebounding from the $83–$86 demand area. Traders now focus on the $92–$95 resistance band; rejection could add short-term selling pressure, while a breakout may open room toward $98 and higher. Keyword focus: Open Wallet Standard strengthens the infrastructure for AI-native finance, while SOL’s near-term direction hinges on resistance at $92–$95.
